The Claim
In adults with amnestic mild cognitive impairment or mild dementia, greater severity of enlarged perivascular spaces in the centrum semiovale is associated with greater cognitive decline over a two-year period, even after adjusting for amyloid and tau burden.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults with early memory problems, more extensive fluid-filled spaces around brain blood vessels in a specific region correlates with faster worsening of memory and thinking skills over two years, regardless of amyloid and tau protein levels.
See the scientific wording
In adults with amnestic mild cognitive impairment or mild dementia, greater severity of enlarged perivascular spaces in the centrum semiovale is associated with greater cognitive decline over a two-year period, although this association is no longer significant after accounting for amyloid and tau burden.
Fluid buildup around brain blood vessels blocks the cleanup system that removes toxic proteins, so amyloid and tau build up, kill brain cells, and make memory and thinking worse over time.
What the research says
1 studyIn older adults with early memory problems, more fluid-filled spaces in a specific brain area are linked to faster memory loss over two years — but only because those spaces are tied to Alzheimer’s proteins. Once you account for those proteins, the spaces themselves don’t seem to cause the decline.
